Pharmacokinetics, Pharmacodynamics, and Safety of NANOKINE Compared With Eprex 4000 U in Healthy Volunteers

This clinical trial aims to compare the pharmacokinetic (PK), pharmacodynamic (PD) parameters, and safety between Nanokine of Nanogen Pharmaceutical Joint Stock Company and Eprex® of Janssen Cilag Ltd on healthy male volunteers. The biosimilarity of erythropoietin (EPO) between Nanokine (test) and Eprex® (comparator) was evaluated in a randomized, two-treatment, two-period, crossover, single-dose study. Subjects received a 4,000 IU subcutaneous dose of either formulation, followed by the alternate after a 28-day washout. Key pharmacokinetic (PK) parameters, Cmax and AUCinf, were assessed, with geometric mean ratios/GMR (90% CI) falling within the regulatory range (0.80-1.25). Pharmacodynamic (PD) marker (reticulocyte count) need to show comparable effects. Safety evaluation (adverse events and serious adverse events, other safety assessments such as vital signs, testing, and examination) supports their interchangeability in clinical use.
